Hi, Bruce!
Yes, it's been 7 years, but I'm setting up a FreeSWITCH system for a local
non-profit, and part of this is FAX.
I have been using your fsfax script at my company for a long time, and they
just keep working, so I never made any changes.
When I was on your GitHub repository (https://github.com/bwmarrin/fsfax) I
noticed the code hasn't been updated for 6 years. Is this because:

1. It's already perfect?
2. You updated it, but forgot to push?
3. You found something better?

Let me know which, so I can decide which FAX solution to use.
